AI choose White as color

Whenever the computer plays this weenie deck I posted, it uses Mother of Runes mostly correctly, except it always gives pro blue for some reason. Even if the player's deck doesn't have any blue.

I don't know if it's a card bug or a AI bug... Just in case, my CPU is Athlon 64 3000+ (real freq. is 2Ghz) and I have WinXP SP3 with 1.5 gigs of RAM. AI think time configured in BotArena was 2 minutes.

From the attached log:

Computer activated Mother of Runes and targeted Isamaru, Hound of Konda(2/2) (gained protection from blue until end of turn)

Even though I don't have any blue anywhere and my only creature is green, the AI uses protection from blue.

Every single time time that it gives protection, it's from blue. That's racism.

It seems to select (only) blue, because this is the first ability of the currently five separate protection from <color> abilities is has.

Iona, Shield of Emeria
I was playing a mono-blue deck.
On turn 16, AI plays 'Iona, Shield of Emeria' (flying 7/7 with chose a color, your opponent can't cast spells of the chosen color) - and chooses white

I noticed recently while using a mono-green deck that the computer always used Sygg, River Guide to give protection from white. I was at 2 life, and it never just gave something protection from green and killed me.

I attributed it to the low thinking time I'd set, but maybe it's a more general AI-hates-white thing.
